Damage Types

Different weapons do different kinds of damage. These in turn require different kinds of resistance to mitigate. Also, you can increase the amount of a particular kind of damage a weapon does by increasing your bonus to that damage type, using either Artifacts or Elite Tech.

DoT

Some weapons have a DoT (Damage over Time) property. Often, their initial damage is low; the DoT is the killer. Examples of stacking DoT weapons are Acid Blaster, Skeletor Lightning, and Plasma Gun. This is not an actual damage type in and of itself; DoT can deal any of the above three damage types.
